The Puppet Murder Case (1935)

Scrappy is running a puppet show for the neighborhood kids. Scrappy won't let his little brother see the show, socking him in the face repeatedly every time her tries. Oopy sneaks in anyway and, using a pee shooter, kills a stageful of puppets by breaking their strings. After Scrappy beats Oopy again, then has the 'puppets' put him on trial. This concludes with a puppet jury deciding Oopy is guilty, sentencing him to more abuse.
